Fixed a problem that could cause Xid errors and display corruption in certain cases when OpenGL is used to render to redirected windows, for example when Java2D is used with the -Dsun.java2d.opengl=true option.

Fixed the timestamp reporting in the GL_NV_present_video extension on SDI II with Quadro FX 4800 and 5800.

Improved power management support on some systems, such as Hewlett-Packard xw4600 workstations.

Fixed a problem that caused the screen to flicker momentarily when OpenGL applications exit unexpectedly on GeForce 6 and 7 series GPUs.

Fixed an X server crash when an X client attempts to draw trapezoids and RenderAccel is disabled.

Improved recovery from certain types of errors.

Fixed a bug that caused Autodesk Maya to freeze when overlays are enabled.

Fixed an interaction problem between OpenGL and memory tracking libraries such as MicroQuill SmartHeap.

Added support for RG renderbuffers in OpenGL 3.0.

Added support for OpenGL 3.0 floating-point depth buffers.

Fixed a problem that caused Valgrind to crash when tracing a program that uses OpenGL.

Updated VDPAU to support VC-1/WMV acceleration on all GPUs supported by VDPAU; see the README for details.

Fixed VDPAU corruption on some H.264 clips.

Updated VDPAU documentation in the README and in vdpau.h, in particular regarding how to use the deinterlacing algorithms in the VdpVideoMixer object. Explicitly documented "half rate" deinterlacing, which should allow the advanced algorithms to run on more low-end systems.

Implemented a "skip chroma deinterlace" option in VDPAU, which should allow the advanced deinterlacing algorithms to run on more low-end systems. See vdpau.h.

Improved VDPAU's handling of some corrupt H.264 streams, and some corrupt/invalid MPEG streams on some GPUs.

Fixed VDPAU to correctly handle WMV "range reduction" on some GPUs. A minor backwards-compatible API change was made for this; see vdpau.h's documentation for structure field VdpPictureInfoVC1.rangered.

Fixed a problem that caused surfaces to be marked as visible too early when the blit presentation queue is in use.

Fixed VDPAU to prevent some cases of "display preemption" in the face of missing H.264 reference frames on some GPUs.
